Abstract

OBJECTIVE: To determine if postoperative soft cervical orthosis use affects arthrodesis rates on a per-level or construct basis after 1-level and 2-level anterior cervical discectomy and fusion (ACDF).

METHODS: Electronic medical records were queried for 1-level and 2-level primary ACDF between 2016 and 2019 at a single academic center. Surgeons prescribed either a soft cervical orthosis or no orthosis. Pseudarthrosis rates were evaluated by dynamic cervical spine radiographs with arthrodesis defined by < 1 mm of interspinous motion. Continuous and categorical data were compared using analysis of variance or χ

RESULTS: A total of 316 unique patients (504 instrumented levels) met the inclusion criteria. Eighty-four percent of patients were prescribed a soft cervical orthosis. Overall, arthrodesis occurred at 344 (80.9%) and 62 (78%) levels in patients with and without cervical orthosis, respectively. When evaluating patients placed in a cervical orthosis versus those who were not, there were no differences in pseudarthrosis or revision rates. Further, there were no differences in pseudarthrosis on a per-level basis. Further, cervical orthosis use was not an independent predictor of pseudarthrosis (odds ratio, 0.86; 95% confidence interval, 0.47-1.57; P =0.623) on multivariate analysis.

CONCLUSIONS: Postoperative placement of soft cervical orthoses after 1-level or 2-level ACDF was not associated with improved arthrodesis or reduced rate of revision surgery.
